A start-up that allows brands to gain insight into customer behaviour by searching for specific spoken words in videos posted online has raised £200,000 seed investment, set to back its expansion into London.

Founded in 2011 by Carl Wong and David Woods, Liverpool-based LivingLens claims to allow brands to understand consumer behaviour to a greater degree than before by transcribing and indexing the content of videos posted online by consumers, allowing clients to search for specific words and phrases.

It was one of the latest cohort of businesses on business-to-brand accelerator Collider, a process that allowed it to take on multi-national consumer brand Unilever as a major client and partner, on its way to amassing other high-profile customers including the Carphone Warehouse, William Hill, TalkTalk and the BBC.

The £200,000 seed round contained input from a consortium of angel investors including two figures connected with Unilever – former senior vice-president of foods Andy Porteous and former board member Ralph Kugler – and Rose Lewis, chief executive of the Collider accelerator.

It is expected to be used to develop its product and invest in sales, in addition to opening a London office later this month.
